Subject: [PATCH 1/4] feat: add JSON-RPC 2.0 hwLedger integration shim
Adds hwledger_rpc.py: line-delimited JSON-RPC 2.0 server over stdin/stdout
for hwLedger inference control. Implements generate, cancel, load_model,
unload_model, memory_report, and health RPCs.
Adds __main_hwledger__.py entry point for invocation as:
python -m omlx.__main_hwledger__
or: uv run --project . python -m omlx.__main_hwledger__
Traces to FR-INF-002 (JSON-RPC over stdio).

+# Session Overview
+
+## Goal
+
+Add the sladge governance badge to phenotype-omlx because it is a local LLM
+inference server with MCP, Claude Code, OpenAI, and Anthropic-compatible surfaces.
+
+## Outcome
+
+- Added the badge to the README badge block.
+- Used isolated worktree `phenotype-omlx-wtrees/sladge-badge` because canonical
+ phenotype-omlx has unrelated untracked worklog files.
+- Kept the change documentation-only.
+
+## Commit Scope
+
+- `README.md`

+# Research
+
+## Repository Fit
+
+phenotype-omlx is an LLM inference server for Apple Silicon. The README describes
+local LLM serving, MCP support, Claude Code optimization, and OpenAI/Anthropic
+API compatibility.
+
+## Local State
+
+The canonical checkout has unrelated untracked worklog files. The rollout used
+`phenotype-omlx-wtrees/sladge-badge` from `main`.
+
+## Governance Context
+
+projects-landing tracks sladge as governance metadata only. This rollout does
+not change runtime code or catalog metadata.

+# Specifications
+
+## Acceptance Criteria
+
+- README includes exactly one `sladge.net` badge reference.
+- The badge appears in the existing badge block.
+- The canonical dirty checkout remains untouched.
+- The commit includes the required Codex co-author trailer.
+
+## Assumptions, Risks, Uncertainties
+
+- Assumption: LLM inference servers with MCP and API compatibility are in scope.
+- Risk: README uses HTML badge formatting rather than Markdown badges.
+- Mitigation: Match the existing centered HTML badge block.

+
+1. Confirm LLM inference scope. `[done]`
+2. Check canonical status and worktree state. `[done]`
+3. Create isolated worktree from `main`. `[done]`
+4. Add README badge. `[done]`
+5. Add session documentation. `[done]`
+6. Validate badge presence and diff scope. `[done]`
+7. Commit documentation change. `[pending]`
+8. Update projects-landing governance ledger. `[pending]`
+
+## Dependencies
+
+- Step 6 depends on README/session docs being complete.
+- Step 8 depends on the badge commit.

+# Implementation Strategy
+
+## Approach
+
+Use an isolated docs-only rollout:
+
+- Add the sladge badge to the existing README badge block.
+- Store rollout evidence under `docs/sessions/`.
+- Avoid runtime, generated, and catalog changes.
+
+## Rationale
+
+The badge marks a direct LLM-serving surface without changing package behavior.

+## AgilePlus Mandate
+
+All work MUST be tracked in AgilePlus:
+- CLI: `cd /Users/kooshapari/CodeProjects/Phenotype/repos/AgilePlus && agileplus `
+- Check for existing specs before implementing
+- Create spec for new work: `agileplus specify --title "" --description ""`
+- No code without corresponding AgilePlus spec
+
+## Worktree & Git Discipline
+
+- Feature work uses repo-specific worktrees: `repos/[PROJECT]-wtrees//`
+- Canonical repo stays on `main` except during explicit merge operations
+
